B1 Primecoat™

1 of 1 products in this brand
B1 Primecoat™ is designed as a high-performance sealer and coating formulated for concrete. B1 Primecoat™ is supplied in a convenient one-to-one mix ratio. B1 Primecoat™ is capable of penetrating and filling the porous structure of concrete in order to provide an effective subsurface barrier to prevent moisture migration, out-gassing, and chemical penetration. Epoxytec B1 Primecoat™ exhibits highly penetrating properties which provide porous filling and strengthening of the top concrete layer to form a sufficiently strong base for subsequent top coats.

Typical Uses
  • Mainly, but not limited to, applications for concrete floors, concrete or brick walls, suitable for any similar architectural or structural concrete structures: pits, mines, tunnels, reservoirs, sewers, or cisterns, etc.
  • Immersion and non-immersion utilization.
  • Epoxytec B1 Primecoat™ is recommended for use on class 1, 2, 3, 4 concrete floors as classified in 1.1 of ACI Standard 302-69.
Surface Preparation
  • Coat only clean, dry surfaces.
  • Remove all grease, oil, dirt or other foreign matter by solvent or detergent washing.

Concrete:

  • Brush-Blast Cleaning (SSPC-SP7) can be used to prepare the concrete by removing all foreign matter and provide profile for bonding.
  • Remove all dust from surface before starting the application of the coating.
  • Epoxytec B1 Primecoat™ is recommended to prime and seal concrete.

Water Blasting:

  • Water Blasting is acceptable ain ordert o meet the standards described in NACE No. 6/SSPC-SP 13, “Surface Preparation of Concrete.”

Previously Painted Surfaces:

  • Remove all rust, rust scale, other corrosion products, loose or heavy chalk and loose or scaling paint by: Hand or Power Tool Cleaning” (SSPC-SP-2 or 3).
  • Brush blast any glossy areas until dull.
  • Spot prime bare areas as recommended and apply one or more coats of Epoxytec B1 Primecoat™ as specified.
  • Check compatibility by applying coating to a representative area and allow to cure and age.
  • Then make cross-hatched cuts through the coating and check adhesion by firmly applying masking tape to the cross-hatched area and removing with a fast pull.
  • If the coating remains intact and there is no wrinkling, lifting, blistering or any other sign of incompatibility present, coating work may then proceed.

Mixing:

  • Material is supplied in 2 containers as a unit.
  • Always mix a complete unit as supplied (3B to 1A by volume).
  • Thoroughly mix B Component before adding A Component.
  • Combine entire contents of Part A and Part B and mix thoroughly with a Jiffy Mixer or equal for 2-3 minutes.

Thinning:

  • Supplied at spray viscosity, requires no thinning.
Application Method
  • Epoxytec B1 Primecoat™ can be applied by brush, roller, or spray.

Induction Time:

  • None required.
  • To obtain maximum edge retention and film build, conventional or airless spray is recommended.
  • Thoroughly flush equipment with solvent.
  • Application by other methods, brush or roll, may require more than one coat.

Roller:

  • Short nap roller cover.
  • Dynel recommended.

Conventional Spray:

  • DeVilbiss MBC-510 gun or equal; E-tip and 704 air cap; 3/8” ID material hose; double regulated pressure tank with oil and moisture separator.

Airless Spray:

  • Minimum 28:1 ratio pump; .013” - .017” orifice tip; ¼” ID Teflon material hose; 90- 100 PSI line pressure.
Limitations
  • Apply in good weather when air and surface temperatures are between 50°F and 100°F.
  • Keep from freezing.
Coverage & Thickness
  • Theoretical coverage will depend on substrate (how absorbent); however, product should be applied at 3 - 4 mils DFT (as thin as possible).
  • The coverage will yield between 300 and 500 square feet per gallon depending on thickness.
